A wedge wire filter element (also called a wedge wire screen or V-wire filter) is a high-performance, durable filter used in industries where strength, precision, and clog-resistance are essential. Let me break it down for you:
What Is a Wedge Wire Filter Element?
It’s a cylindrical or flat filter screen made from triangular (V-shaped) stainless steel wire, welded onto support rods. The V-shaped wires are spaced precisely to form a slot that filters solids from liquids or gases.
Key Features
| Feature | Benefit |
| V-shaped wire | Minimizes clogging – particles can’t get stuck easily |
| Precision slots (0.02mm to several mm) | Accurate filtration size |
| Strong & durable | Handles high pressure, heavy flow, and backflushing |
| Corrosion-resistant | Usually made from 304 or 316 stainless steel |
| Easy to clean | Ideal for backwashing or ultrasonic cleaning |
Common Shapes
Cylindrical – Used in filters, strainers, screens
Conical – Used in specialty filtration systems
Flat Panels – For screens or floor drains
Baskets or Tubes – For vertical filtration
Where They're Used
Wedge wire elements are incredibly versatile and used in:
Water Treatment
